DICE is taking the single-player campaign of Battlefield 3 very seriously - so much so that the studio is creating totally unique levels for both solo and co-op campaign modes."They’re completely different, and they’re all completely different from one another," said the lead designer David Goldfarb. "Single-player has its own campaign arc, and multiplayer has its arc, which uses some of the context of the SP but in its own way."
The multiplauer co-op breaks free from the storyline of the single-player, according to Goldfarb, by "looking forward into the future to what might happen, and so we give people a bit more of a fantasy. I guess you could say that MP might be where SP leaves off in some cases. The reasoning is to give people enough latitude as they can have to design the maps."
Goldfarb also revealed that the campaign won't be a short one - "I would say it’s a pretty decent length. It’s not Skyrim, but it’s not three hours, or anything like that. I’m not sure, as we’re still working on the difficulty balancing, and that seems to make the pendulum swing quite a bit."
